Windshield washing system for a windshield of an automobile

Abstract

A windshield washing system for a windshield of an automobile is connected to a vessel which collects condensed water from an air conditioning system. A pump feeds the condensed water to washing nozzles arranged in front of the windshield. Collecting the condensed water largely avoids laborious manual topping up of the vessel.

1 . A windshield washing system for a windshield of an automobile, comprising: 
 a first vessel for collecting liquid to be sprayed onto the windshield;    a pump for feeding the liquid from the first vessel to a washing nozzle configured for directing liquid flowing therethrough onto the windshield; and    feed means connectable to an air conditioning system in the motor vehicle for feeding condensed water from the air conditioning system to the first vessel.    
   
   
       2 . The windshield washing system of  claim 1 , further comprising a condensed water outlet of the air conditioning system, wherein the condensed water outlet of the air conditioning system is arranged above said first vessel.  
   
   
       3 . The windshield washing system of  claim 1 , further comprising a second vessel and a suction line connecting the second vessel to the first vessel, wherein the pump is configured to draw condensed water from the first vessel.  
   
   
       4 . The windshield washing system of  claim 1 , wherein the first vessel has a filling connector for receiving liquid manually.  
   
   
       5 . The windshield washing system of  claim 1 , wherein the first vessel has a filling level sensor and a control device connected to the filling level sensor, and wherein the control device is configured to actuate the air conditioning system when the filling level in said first vessel drops below a minimum filling level.  
   
   
       6 . The windshield washing system of  claim 3 , wherein the pump is a double acting piston pump configured to fill the second vessel and feed the condensed water to the washing nozzle.  
   
   
       7 . The windshield washing system of  claim 1 , further comprising an additional vessel for an additional substance, a metering pump connected between the first vessel and the additional vessel and configured to feed the additional substance to the first vessel.  
   
   
       8 . The windshield washing system of  claim 3 , wherein at least one of the first vessel and the second vessel has a filling connector for receiving liquid manually.  
   
   
       9 . The windshield washing system of  claim 3 , wherein the pump is configured to draw in condensed water from the first vessel as a function of the filling level in the second vessel.
